intramolecular Suzuki-Miyaura reaction of linear tripeptide (23) afforded the 16-membered DEFG ring of complestatin (3) in good yield with an excellent atropdiastereoselectivity. Acidic treatment of 3 triggers a stereospecific rearrangement leading to the corresponding DEFG ring 4 of chloropeptin I.
                                    钯催化的线性三肽的分子内Suzuki-Miyaura反应(23)以良好的收率和优异的阻转非对映选择性提供了补全他汀(3)的16元DEFG环。3的酸性处理会触发立体特异性重排,导致相应的
氯肽I的DEFG环4。
